Solar photovoltaic capacity (PV) will soon match and even overtake nuclear energy’s global capacity, according to new US research. High demand means PV could even become the globe’s dominant energy source by 2050. By the end of 2017, solar power plants around the world are predicted to have an installed capacity of 390GW, according to estimates by Greentech Media. That is just shy of the 391.5GW of nuclear capacity currently in operation. GTM’s research shows that, for the very first time, solar and nuclear capacity will be on equal footing and demand in China could even push photovoltaics beyond atomic capacity by year’s end.
